Just note down the headings and nav aid frequencies from your flight plan, then tune the Nav 1 radio and twirl the course onto the required heading, watch the distance count down and when you get over the nav aid, tune the next one in your flight plan list and dial in the course to that, rinse and repeat until you get to a final approach fix and then head for the airport and take her in by hand. From VOR to VOR is not really that hard to do, you can use the autopilot to help you if you like, or fly it by hand all the way, either works.If you want to use INS, it is essentially the same as an FMC plan except you key in the nav coordinates in sequence instead of picking waypoints. The CS 727 doesn't have the CIVA INS by default, but you can add it yourself, or if you have the ISG add on gauges, you could even put an FMC in the cockpit of the 727. Of course it has no autothrottle, but it's not hard to work that manually.Al

Al I have the ISG, what is the best fmc to add? What fmc do 727's use? Do you have it setup and if so can I see your panel config?

Few Boeing 727s were ever really fitted with a true FMC and I personally prefer it without one, which is ironic because the B-727-200 was one of two aircraft types (the other was a 737-200ADV) which Boeing and Lear Seigler used to trial the very first of what would later be called the FMC. so technically, the 727 has a good claim to being the first aircraft to ever have an FMC.At that time (late 70s) it was called the PDCS (Performance Data Computer System), but there was no such thing as an autothrottle for the 727 back then (or any other Boeing for that matter), so the PDCS only controlled a few parameters, and most of that was by means of 'advisaries' by moving motorised bugs on the dials rather than actual automated control, the main things which had that happen being the EPR and ASI although the system also advised on the best flight level to be at for maximum fuel economy.All of that stuff resulted in the 727-200 showing about a four percent improvement in fuel economy when using the system. Testing was completed by 1980, and by 1982 the autothrottle had been devised to link the FMC to the throttle. Some Continental 727s were retrofitted with the PDCS, but the 727 never really fully benefited from the FMC because it was out of production two years after all of that stuff was really finalised as a design, nevertheless, some posh 'private' 727s and a few airline ones have had custom third party systems fitted these days, so it is not totally unrealistic to have an FMC in a 727, just rare (especially today since they are being mothballed or scrapped nowadays).As far as fitting an ISG FMC in your CS 727 goes, since it would effectively be simulating a custom avionics fit, you can put what suits you best, and I reckon out of what is in the ISG package, that would be the Smiths one, although technically a 727 would probably have a custom fit, so you could use the GNSXLS just to be different, the real thing is likely to have probably one of these things: http://www.uasc.com/products/mcdu.aspxYou might want to look at this document too for information on how that Universal system adds capabilities to a 727 via their FMC and EFIS gear, so you know what and what not to enable in ISG if you want the thing to realistically emulate what that really makes a 727 capable of: http://www.uasc.com/documents/newsletters/4Q09_UniversalFlyer.pdf#search=%22727%22Never actually tried to fit one in the CS 727 myself, although I can't imagine it would be problematic to do so, although there's no really suitable slot for it in the VC, so I think you'd be looking at a 2D pop up panel. Personally, if I was going to try it, I'd fit the GNSXLS just to make it noticeably different from a 737 so it really did look like a custom avionics fit.Al

Thanks for the tips, I am fine with just putting the fmc to replace the default gps window.I assume I have to add the isg eifs panel and press an lnav and vnav button? Is there any fmc that works by just pressing gps on the captain sim ap panel?I'd love to find out what someone like Morningstar, Kelowna, Amerijet, Cargojet, or another current operator flys with.

DHL used the Universal UNS-1E in their 727s. That would be this one:http://www.uasc.com/products/uns1ew.aspxTo fit the ISG FMC in a non FMC-equipped aircraft, you have to add the FMC plus LNAV and VNAV buttons, and you have to alter the ISG config file by adding the parameters you want to enable. You will probably also need to add a PFD so that the mode the FMC is in is correctly annunciated. The ISG MCU will do GPS navigation if you want a simpler option. There is an Aerosim 727 retrofit listed here on the ISG site too, you could modify that for the CS 727:http://isgsim.com/?page=panel_library⊂=retro_aerosim_b722Al

For what it's worth, you don't really need to add the NAV/GPS button in order to couple your GPS to the AP. All you need to do is assign a key combo to that function in your control settings/assignments, and just use that. You just have to remember to click it off when you are ready to approach and land. But learning the old school way is fun.

I agree, I'm not sure why people are so worried about using VOR and INS navigation, it's still pretty much the basis of most flying that gets done around the world in spite of the advent of GPS and GLONASS, and unlike those (which literally do involve rocket science LOL), it's not that hard to get into.Al

i try vor navigation, bird shaking very much. and i couldn't ils landing.can you wirte down step by step how to capture localizer and glide slope?

A bit of reading for you, Cenk. :smile:The general 727 thread can be found here and could be useful. What definitely will be useful for you is the dedicated Autopilot thread over there. Find it here.What mixes most people up on the 727 is the fact that the Flight Director and the Autopilot work separately and not always linked to each other like on newer planes. So doing an ILS landing usually means that the FD and the AP have to be in the same mode. You will see the announcer lights coming up then. First, they are "armed" (orange) and later they are active (green).Find more details on this mentioned Autopilot thread or the general 727 section.
